Cause keypresses to reset the screen in case we are in scrollback (previously
the screen was only restored if a new character was actually displayed on the
screen); jcs@rt.fm. This brings us closer to the behavior of PCVT. Also, while
I'm here, add some #ifdef so wskbd does not depend on wsdisplay (pointed out
to me by fgsch@).
